Replacing brake discs on Hyundai i30. Replacing brake discs on Hyundai i30 Repair and maintenance of calipers

State brake system directly affects traffic safety. If brake pads or the discs become unusable, the car's controllability decreases, and this can lead to an accident.

To ensure braking performance remains at high level, it is necessary to periodically diagnose the brakes and, if significant wear is detected, immediately replace the brake discs or pads. If you take care of your brakes and have them repaired promptly, you will never have to worry about safety on the road.

Brake disc replacement technology

Replacing rear brake discs, like replacing the front ones, is a fairly simple but labor-intensive process that requires experience and training. Depending on the brand of machine, the technology of work may differ slightly, however general rules Brake repairs are the same for all cars:

Remove the wheel.
Depress the piston and move the caliper to the side.
Unscrew the disc from the hub.
Dismantled brake disk.

After installing the disk, reassemble what was disassembled in the reverse order. Replacing front brake discs is virtually the same as replacing rear brake discs, except that the caliper may be positioned slightly differently.

Please note that discs on the same axle must be changed at the same time, otherwise the difference in the thickness of the working surface will affect the braking efficiency. After the discs have been replaced, the pads are checked; if they are worn out, they are also replaced.

Signs of faulty brake discs

The frequency of replacing discs and brake pads depends not on mileage, but on wear. This means that higher quality pads can last much longer than cheap duplicates.

Signs of faulty brake discs:

Increased braking distance.
Reduced level brake fluid.
When braking, the car pulls to the side.
Beating in the brake pedal and steering wheel at the same time.

Discs become unusable if you brake frequently and harshly. Also, sudden changes in temperature are harmful to the discs - for example, if you sharply press the brakes in front of a puddle and then drive into the water, the hot metal can become deformed.

Prices for replacing front and rear brake discs in Moscow

The cost of replacing brake discs consists of labor costs and the price of spare parts. You can buy everything inexpensively from us necessary details for repairs of any complexity. Price repair work also low when compared with average prices in the city. Call us and we will tell you the estimated cost of the services you are interested in.

Repair always begins with diagnostics. If necessary, it is carried out on a special brake stand, allowing you to track the residual life of all components and assemblies of the brake system of the Hyundai i30.

And upon completion of most operations, it is necessary to bleed the brakes, releasing air from the system.

Replacing brake fluid

The manufacturer recommends replacing the brake fluid in a Hyundai i30 car at least once every 2 years. This is due to the fact that even if there is a sufficient level of it in the system, working in an aggressive environment leads to a loss of basic properties.

Our masters will sequentially drain and pump it out as if from brake cylinders, and from the brake barrel, they will fill in a new one, and then bleed the car’s brake system and check it for leaks.

Repair and maintenance of calipers

The calipers themselves in most cases are almost eternal. They usually have to be replaced after an accident, for example when a caliper bracket breaks or in the event of very heavy wear caused by rust. In all other cases (and there are many of them), the calipers on the Hyundai i30 are repaired.

The caliper is removed from the car and disassembled. Both individual parts (pistons, gaskets, fittings) and complete assembled repair kits are available for sale. The caliper itself is cleaned of rust, if necessary, sharpened on a machine, and after replacing the internals, it is installed back.

For all types of work on repairing the car’s brake system, replacing brake pads, discs, brake fluid, calipers, a repair guarantee is provided. In stock wide choose original and not original spare parts. We at the Hyundai car service network are ready to carry out repairs on the day of your call and at reasonable prices.

If there are scuffs, deep scratches and other defects on the working surface of the disc that increase pad wear and reduce braking efficiency, as well as in the case of increased lateral runout of the disc, causing vibrations during braking, replace the disc.
The minimum permissible brake disc thickness is 8.4 mm. If one of the discs is less than the specified thickness, replace both discs. When replacing brake rotors, be sure to replace the brake pads with a new set.

You will need a Phillips blade screwdriver.

1. Remove the wheel from the side of the disc being replaced.

2. Remove the caliper without disconnecting the hose from it (see “Replacing the caliper brake mechanism rear wheel").

3. Tie the caliper with wire to the spring to keep it from falling...
